Bohai-Rim Region as economic growth pole is accelerating the progress of urbanization. The paper will guide the healthy development of the region spatial extension by green smart growth, as well as solve the regional trouble of ''city disease''.

Abstract

Bohai-Rim Region is located in the Pacific West BankúČis the center part of the increasingly active Northeast Asia economic zone. The region includes the three provinces and two cities. They are Beijing city, Tianjin city, Hebei province, Shandong province and Liaoning province. These provinces and cities are accelerating the progress of urbanization.With the rapid progress of the regional urbanization, while human beings enjoy the civic life of modern cities, they had to face the troubles and cruces coursing by urbanization, especially the trouble of ''city disease''. How to guide the healthy development of the region spatial extension by green smart growth. As well as we solve the city disease. The paper proposes three strategies. The first, the regional space is divided into four areas: ecological protection area, control the development area, optimally enhance the development area and key development areas. For regional land use, urban development boundary identified to prevent excessive expansion of large urban area, protection of natural environmental resources. The second, communicating the regional urban green corridors, maintenance and increase of the opened space connectivity, establishing green nodes, enhancing diversity and complexity of the green network. The third, determine the eco-coordination areas in the region and proposed ecological compensation measures from the watershed scale, regional scale. In order to set up a perfect mechanism of eco-compensation, achieve the balance between environmental protection and economic development.
